The hemolytic - uremic syndrome (HUS) presents with a triad of acute renal failure, microangiopathic hemolytic anemia and thrombocytopenia associated with high morbidity and mortality. On the differential diagnosis, other entities must be considered like preeclampsia, HELLP syndrome, acute fatty liver of pregnancy and thrombotic thrombocytopenic purpura. We report a case of HUS occurring in the immediate postpartum period in a patient initially diagnosed as having preeclampsia. The differential diagnosis was based on abrupt renal failure, blood pressure increase and clinical and laboratorial evidence of hemolysis. Attention is directed to investigation, clinical management and prognosis based on review of the literature.
